Borel约简提供了一种方法,证明某些问题是不可能的,使用基于可数信息的可数无穷技术,并为分类问题提供了一个难度层次。这是说明与例子,包括最近的结果,在动力系统的分类问题提出的冯诺依曼在1932年是不可能解决的固有可数工具。
Borel reductions provide a method of proving that certain problems are impossible using countably infinitary techniques based on countable information and provide a hierarchy of difficulty for classification problems. This is illustrated with examples, including a recent result that a classification problem in dynamical systems proposed by von Neumann in 1932 is impossible to solve with inherently countable tools.
